MEDICATION (VET): The effects of amrinone and calcium chloride on pulmonary vasculature and biventricular function in sheep with acute lung injury were studied. Seven sheep were ventilated with a tidal volume of 10-12 sq ml of 40 + or - 5 mm Hg (5.3 + or - 0.7 kPa) after acute lung injury was induced with up to 30 mg/kg of ethchlorvynol. Raman spectra and 17 O NMR of CaCl 2 and MgCl 2 solutions with concentration below 1.0 mol/l are measured, and the Raman spectra are deconvoluted into components whose center frequency are 3051, 3233, 3393, 3511, 3628 cm −1, respectively.

The effect of calcium chloride (CaCl2) on tricalcium silicate (C3S) hydration was investigated by scanning transmission X-ray microscopy (STXM) with Near Edge X-ray Absorption Fine Structure (NEXAFS) spectra and 29Si MAS NMR. STXM is demonstrated to be a powerful tool for studying the chemical composition of a cement-based hydration system.

M. Monteiro In this study, we show that the NMR data do indeed support the prominent axial positioning of the methyl groups in the CaCl2 and Ca(NO3)2 complexes of I and II in solution. Furthermore, the NMR data are consistent with the assertion that the S chiral ring twists in an opposite sense to the R chiral ring in these complexes. Mobility of water molecules in nanocrystals and other phases of CaCl2·xH2O (x=0–12) formed in the nanopores of silica gel during sorption of water vapor is studied by1H NMR. Fig. 2.

Dynamics of water molecules in hydrates dispersed in the mesopores of silica are compared with those in the bulk state. Analysis of the 2H NMR line shape and T1 and T2 relaxation times allowed us to characterize the water mobility in a wide temperature range The 29 Si MAS NMR analysis reveals that the presence of CaCl 2 in hydrated C 3 S accelerates the formation of middle groups and branch sites in the silicate chains of C-S-H gel considerably, in agreement with increasing the degree of polymerization of the silicate chains in C-S-H gel considerably.
